The Pennington SWCD has collaborated with Pennington County for several years to identify priority County Ditch reaches that are in need of buffers and grade stabilization structures. This cooperative effort has resulted in the reduction of nutrient and sediment delivery to the Red Lake River Watershed. Pennington SWCD has recently inventoried buffer and grade stabilization needs on three different County Ditch systems: 96, 21 and 16. A total of 23 miles of ditch has been inventoried, 15 miles of buffer are needed along with 81 grade stabilization structures.
Sediment and water quality issues are local priorities within the Thief River and Red Lake River watersheds, which have their confluence in the city of Thief River Falls. The 1W1P effort underway in the Red Lake River Watershed will identify opportunities for projects and practices that are targeted and result in measurable water quality benefits throughout the watershed using PTMApp.
This project Phase will collect data, background information, and watershed characteristics within the Red Lake River watershed. This information will be documented within the framework of early draft TMDL Reports (with background information, but no load calculations) for impaired reaches within this watershed and early draft protection plans for the areas in the watershed that are not currently impaired.
The purpose of this project is to improve understanding of primary productivity in the Red River and the diversity and population structure of the algal communities occurring along the river system. This will be accomplished through taxonomic identification of periphyton and phytoplankton assemblages necessary for characterizing responses to nutrient gradients along the Red River of the North.
The International Water Institute (IWI) will monitor 42 sites (3 basin, 12 major watershed, and 27 subwatershed) in the Red River and Upper Mississippi River Basins intensively during 2016, 2017, 2018 and 2019. There will also be 5 sites in the Red River Basin where mercury samples will be collected in 2016 and 2017 and sent to Minnesota Department of Health for analysis. The IWI will collect water samples across the range of flow conditions targeting sample collection at times of moderate to high flow.
